ANTIFRICTION-TRANSFER FOR SHOES.

inseam.

To all role/om it may concern:

Be it known that I, J orrn A. CASEY, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented new and useful Improvements in Antifriction-Transfers for Shoes, of which the following is a speciiication.

My invention relates to an improved article of manufacture which is adapted by the application of heat and pressure to attach an antifriction surface to the inner surface of the heel of a shoe, boot or slipper. it is well known that the linings in the backs of shoes and other footwear and the heel portions of hose wear quickly, due to the rubbing action and friction occurring when shoes are worn, and it is the primary objectof this invention to reduce this wear to a minimum and prevent rubbing and chafing of the skin of the heel portion of the foot, in a simple and inexpensive manner. To this end, my invention is a new article of manufacture consisting of a strip or plate of cotton flannel or other suitable material forming a base element coated with a suitable antifriction transfer material such as paraffin or other suitable material which at. normal temperature remains solid but which, by the application of suitable heat and pressure against the base when the article of manufacture is placed in the shoe against the heel surface to be treated, will nielt and transfer the antifriction material to and coat said surface, after which the base removed leaving the antifriction material deposited in solidified condition upon the treated surface.

in the accompanying drawing forming part of this specifi ration Figure l is a plan of my improved transfer, and Fig. 2 1s a side elevation of a detail portion of a shoe, partly broken away and in section, showing my improved transfer in position against the heel surface in a shoe in readiness to apply the antifriction material when heat and pressure are applied.

My improved transfer base A is suitably shaped to be adjusted against the inner surface of the heel of a shoe over its lined portion which ordinarily is subjected to most of the wear, due to the movement of the heel of the foot in the shoe. This base member has substantially a straight lower edge 2 and a curved upper edge 3, although this a nd con veui cntly Specification of Letters Patent.

shape may be variously modified to conform more particularly to the portion in the shoe which it is desired to treat with the antifriction material; .lhis pl ate or base coated or satu *ated with parailiueithcr by brushing molten paraffin over its surface and cooling or by soaking the base in the molten parallin after which it is allmved to solidify. It is preferable to coat only one side of the base A although as stated the entire device can be saturated with the paraflln. In F 2 of the drawing the coated side 4- is shown placed against the lining 5 of the back of the heel 6 of the shoe and 7 indicates the wall of the base A.

When it is desired to treat a worn surface in a shoe such as 13 with the antifriction material the base element is placed over the surface to be treated such as the heel por tion (3, with its paraffin coated side a resting against said surface, after which a hot iron is rubbed over the inner surface of the base until the parallin is melted, whereupon, due to the pressure exerted by the iron against the base, the paratlin is transferred onto the surface of the lining in the shoe which is treated. After the hot iron has been removed the base is stripped and removed from the shoe leaving the solidified paraflin coated over the lining or worn surface in the shoe. This coating;- being of anti friction material serves to reduce wear and friction of the heels of hose and chafing of the skin of the foot, and it also serves to seal and hold the frayed edges of holes in the lining on the leather inner surface of the shoe, when the lining is worn.

While I have specified cotton flannel as suitable material out of which to construct the base it will be understood that other flexible materials may be employed for that purpose; also that instead of using parafiin -aX, any other suitable antifriction adhesive material may be employed which can be transferred from the base onto the inner surface of the shoe by the application of heat and pressure, within the spirit of my invention.

The materials mentioned permit of placing the base elen'ients coated with parallin in envelope convenient for distribution and the low cost of'preduction lends greatly to the filling of along}; felt want for quickly treating linings in shoes and of repairing worn inner surfaces by the users without having to employ shoe cobblers at increased expense and loss of time.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An improved article of manufacture consisting of a flexible base shaped to cover the inner heel surface of a shoe to be treated and coated with an adhesive antifriction transfer medium on its surface to be applied to said heel surface.

2. A transfer for shoes consisting of a flexible base shaped to conform with the inner surface of the shoe to be treated, said base being coatedwith an antifriction transfer medium on the side lying adjacent to said surface, said transfer medium being adapted to be melted by the application of heat to the inner surface of said base.

3. A transfer for shoes consistin of a cloth base approximating the size and sha e of the surface to be treated in the shoe, said base being impregnated with paraflin and adapted by the application of heat and pressure to its inner surface while in the shoe to coat the melted paraflin on said surface.
